To all whom it may concern.-

Be it known that 1, ROBERT T. DARRAH, of

Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Revolv ing Goal Chutes and Cribs; and I do hereby declare the following to be a full, clear, and ex, act description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same. This invention relates to unloading devices; and it consists, essentially, of a revolving coal chute and crib comprising adjustable parts adapted to be directed at any angle from a wagon or vehicle to which it is attached.

The invention further consists of the details of construction and arrangement of the several parts, which will be more fully here:

inafter described and claimed,

The object of the present invention is to provide an attachment especially applicable to coal-wagons or analogous vehicles in the nature of a telescopic chute carried by a revolving crib which is attached to receive the said chute when folded and be turned under the body of the wagon or vehicle to direct the run of or delivery of coal at any desired point and avoid blocking a street or thoroughfare.

In the accompanying drawings, Figure 1 is a perspective view of a portion of a wagonbody, showing the improved rotatable crib attached thereto and the coal-chute extended in operative position. Fig. 2 is a detail perspective view of the crib holding the folded chute therein and shown disconnected from the wagon-body. Fig. 3 is a central longitudinal vertical section through the crib and the folded chute-sections therein.

Referring to the drawings, wherein similar numerals of reference are employed to indicate corresponding parts in the several views, the numeral 1 designates awagon-body having at one end thereof a delivery-spout 2. The form of the wagon-body and of the spout is immaterial, as the improved device is adapted tobe applied to any form of wagon now in use, and has attached to the underside thereof a pair of parallel guides 3, with grooves 4: in the inner edges, which adjustably receive the opposite ends of a supporting-bar 5. The guides 3 extend a suitable distance portion, and has a pivotebolt 8 rotatably mounted therein, which extends through the upper portion of a crib 9. The opposite sides of this crib are supplied with suitable pivot plates orarn'1s 10, to which chains'll are secured and areadapted to hold the chute in closed position within the crib and also may be placed over theopposite sides of the adjacent chute-section to steady and reinforce it. The opposite sides of the wagon-body or an adjacent portion of the frame will also be provided with suitable staychains 12 and also with eyes 13, to which the chains 11 may be secured in holding the crib in its adjusted position. The chute in this instance is tele- .scopicin its construction and arrangement and consists of four sections 14, 15, 16, and 17. The section 14 is st-ationaryin the crib 9 and is arranged normallyat an angle of inclination, its rear or inner end being secured to the top portion of the crib, and each of the sections 15,16, and 17 have oppositely-positioned flanges 18, with slots19. therein. The sections 14', 15, and 16 have flat-headed rivets 20 in the front portions thereof which engage the slots 19, and when the sections of the chute are distended the end of one overlaps the adjacent end of the other, and when telescoped they move regularly one under the other. At the rear upper portion of the flanges, on the sections 16 and 17, upwardlyprojecting inwardly-extendingretention-arms 21 are located and hold the several sections against too much play and relieve the rivets 20 of a portion of the strain brought to bear thereon through the weight of the several sections. Attached to the front end of the chute 17 are adjustable loops 22, adapted to be e11- gaged by the said chains 11 to hold the chutesections within the crib when folded and against accidental disconnection through'vibration or movement of the wagon or vehicle carrying the same. The upper part of the crib 9 is open at various points to not only lighten the structure, but to form arms 23, with a slightly-raised center for connection with the pivot-bolt 8, and insure an easy rotation of the crib without catching or jarnming at any point. All the connecting rivets or bolts have the heads and ends thereof flattened, so as to prevent the formation of pro jections which might catch on the several parts and interfere with the desired adj ustment.

The several chute-sections, as well as the crib and other parts, are preferably constructed of steel to resist wear and to be thereby reinforced against breakage by shocks and ars.

In operation the crib 9 can be turned from either side of the vehicle as far as the running-gear will permit; but the parts are so arranged through their several adjustable features that the angle of adjustment can be varied at will without interfering with any part of the wagon or vehicle. Then the chute is regularly arranged in connection with the end of a wagon, the supporting-bar 5 is moved outwardly in its guides and the crib turned thereon to direct the chutes to the desired point. Then not in use, the chute-sections are telescopically folded into the crib and the latter then adjusted under the wagon bed or body, the several parts being locked and supported during distention and inclosure by the stay-chains, as set forth.

It is obviously apparent that many changes in the construction and arrangement of the several parts might be made and substituted for those shown and described without in. the least departing from the nature or spirit of the invention.

Having thus described the invention, what is claimed as new is 1. In a device of the character set forth, the combination of a revolving crib, and a telescopic coal-chute carried thereby, substantially as and for the purposes specified.

tions movable into and outward from the said minor forth, substantially as and for the purposes 5.- In a device of the character set forth, the combination of a rotatable crib having a stationary chute-section mounted therein at a downward angle of inclination, and telescopic sections attached to said stationary section and to each other and adapted to telescope into said crib, substantially as and for the purposes specified.

6. In a device of the character set forth, the combination of a wagon bod y having staychains and attaching devices on parts thereof, an adjustable crib mounted in connection with said body also having stay-chainsthereon, and telescopic chute-sections carried by said crib and having-devices at the outer end of the outermost section adapted to be engagedby portions of said stay-chains, said chute-sections being adapted to slide into said crib, substantially as and for the purposes specified.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
